Push-fit shield and method for fabricating same

An EMI/RFI shield comprises a frame and a push-fit lid. The frame includes a frame top wall having outer frame edges jointly defining a frame perimeter of predetermined configuration in plan view, and a plurality of side walls depending from the frame edges. The lid includes a frame cover wall having free edges jointly defining a cover wall perimeter complementary in configuration in plan view to that of the frame perimeter, and a plurality of elongated spring fingers formed integrally of the cover wall and extending from the free edges. The fingers are configured to extend laterally beyond said frame perimeter and then downwardly and inwardly to engage the side walls when the lid is fit on the frame. At least some of the fingers have contact portions that are received in slots provided in the frame side walls.
